This document describes the minimum API that needs to be implemented for classes that can be used as buckets (more or less: leaf nodes) in the spatial index. See the main documentation in Algorithm::SpatialIndex for an explanation of how alternative bucket implementations can be used.

Read/write accessor for the array ref (or undef if not initialized) of items in this bucket. An item is defined to be an unblessed array references containing the item id followed by the item coordinates. The type and number of coordinates may depend on the chosen index Strategy. Cf. the strategy's item_coord_types method.
